Abstract: An assist device for a knee joint is provided. The assist device includes a knee joint assist mechanism including a first bracket connected to a waist fixation mechanism and fixed to the lower limb and arranged along the user's thigh, a first spacing adjustment member pivotally connected to one end of the first bracket, a second bracket arranged along the user's calf, and a second spacing adjustment member pivotally connected to one end of the second bracket, in which the first spacing adjustment member and the second spacing adjustment member are engaged with each other, and respectively have coupling structures with different sizes. When the knee joint is in an extended state, the first spacing adjustment member and the second spacing adjustment member have a larger center distance formed therebetween, such that support is provided to the user's knee joint to reduce wear and defect thereof.

The palladium complex has a chemical structure of ?in which X is halogen, each of R1 is independently C1-8 linear alkyl group or C3-8 cycloalkyl group, and each of R2 is independently H or C1-4 alkyl group.

Abstract: The invention provides a corneal path one-way aqueous humor drainage device, in which a Tesla valve unit group drainage channel is formed for draining aqueous humor to the ocular surface, and the drainage channel is a one-way drainage. The aqueous humor diverter provided by the utility model introduces a Tesla valve as a structure to prevent the backflow of aqueous humor. When the liquid flows into the Tesla valve unit group from the liquid outlet, the Tesla valve unit group can block the liquid from entering the liquid. Oral flow. The aqueous humor drainage device can be used for glaucoma patients to reduce intraocular pressure and can also be used for severe dry eye; it is made of materials with good biocompatibility and has high clinical drainage efficiency; its structure.

Abstract: A method for operating a reticle inspection system includes training an analysis model of the reticle inspection system with a machine learning process, generating a difference threshold based on the machine learning process, storing a reference image, and generating a scan image of a reticle with the reticle inspection system. The method includes generating a relative difference value by comparing the scan image to the reference image. The method includes, if the relative difference value is less than the difference threshold, determining that the reticle is not defective. The method includes, if the relative difference value is greater than the difference threshold, determining that the reticle is defective.

Abstract: In an embodiment, a magnetic assembly includes: an inner permeance annulus; and an outer permeance annulus connected to the inner permeance annulus via magnets, wherein the outer permeance annulus comprises a peak region with a thickness greater than other regions of the outer permeance annulus.

Abstract: Silicon-substituted rhodamine compounds are disclosed herein. Also described herein are SiR dyes comprising at least one vinyl group attached to the Si atom (10 position) of the SiR dye. Derivatives, functionalized versions, conjugates, kits, related synthetic methods and uses of SiR compounds also are provided. Silicon-rhodamine (SiR) dyes can provide bright fluorescence at far red wavelengths and exhibit good photostability. The compounds described herein can be useful for fluorescent labeling and detection of biological samples.

Abstract: A reticle carrier described herein is configured to quickly discharge the residual charge on a reticle so as to reduce, minimize, and/or prevent particles in the reticle carrier from being attracted to and/or transferred to the reticle. In particular, the reticle carrier may be configured to provide reduced capacitance between an inner baseplate of the reticle carrier and the reticle. The reduction in capacitance may reduce the resistance-capacitance (RC) time constant for discharging the residual charge on the reticle, which may increase the discharge speed for discharging the residual charge through support pins of the reticle carrier. The increase in discharge speed may reduce the likelihood that an electrostatic force in the reticle carrier may attract particles in the reticle carrier to the reticle.
